Description: | Incorrect calibration factors caused error in irradiance data for down_short_diffuse_
hemisp, down_short_hemisp, short_direct_normal.
Diffuse:
Data file has correct serial number (33238) but wrong calibration factor.
Wrong diffuse calibration factor is 110.28 when it should be 110.03
Global:
Data file has the correct serial number (30812F3) but wrong calibration factor.
Wrong global calibration factor is 128.79 when it should be 128.74
NIP:
Data file has the correct serial number (29851E6) but wrong calibration factor.
Wrong direct calibration factor is 118.17 when it should be 118.37

Perform the following calculation to correct the data:
DD= down_short_diffuse_hemisp:
Instrument: SN 33238
Old (incorrect) CF: 110.28 [W/m2\mv]
New (correct) CF: 110.03 [W/m2\mv]
DD (new) [W/m2] = DD (old) [W/m2] * 110.03 [W/m2\mv] / 110.28 [W/m2\mv]
-----------------------------------------------------------------------------------
Global:
Perform the following calculation to correct the data:
DS= down_short_hemisp:
Instrument: SN 30812F3
Old (incorrect) CF: 128.79 [W/m2\mv]
New (correct) CF: 128.74 [W/m2\mv]
DS (new) [W/m2] = DS (old) [W/m2] * 128.74 [W/m2\mv] / 128.79 [W/m2\mv]

NIP:
Perform the following calculation to correct the data:
NIP= short_direct_normal
Instrument: SN 29851E6
Old (incorrect) CF: 118.17 [W/m2\mv]
New (correct) CF: 118.37 [W/m2\mv]
NIP (new) [W/m2] = NIP (old) [W/m2] * 118.37 [W/m2\mv] / 118.17 [W/m2\mv] |
